Fantasy Life [3DS]
I still have Xenoblade Chronicles X and Yoshi's Land pre-ordered from last year's E3 [Futureshop], although I'm not sure if they'll honor them now with the name-change. I hope they do, given the cheaper price they're pre-ordered at. I might pre-order those two, along with Persona Q [to keep my Premium Edition sealed], at BestBuy just for safety reasons, and cancel them later if Futureshop confirms that they'll be honoring them.
I also want to pre-order Akiba's Trip - Undead and Undressed [haven't decided whether I'll go with Vita or PS3 yet] but Amazon.ca isn't showing the promotion and BestBuy/Futureshop don't have it listed. Captain Toad: Treasure Tracker, Kirby and the Rainbow Curse, and Mario Maker I'd like to add to my "ordered list", but I don't trust the higher prices that are listed for them now and I don't want the hassle of having to email/contact them to have the price(s) adjusted. I might just wait and see if the prices change first.
As for Zelda U, I'm definitely grabbing this one, but I don't want to pre-order the standard edition since I have a feeling a very nice "Limited Edition" will be made available, and I'd likely want that one instead. I'm not sure, though, Nintendo doesn't exactly do many Limited Editions...
